IMPROVEMENT IN JOURNALS AND BEARlNGS.

Specification forming part of Letters Patent No. 147,67., dated February17, 1674,' application filed December 13, 1873.

To all whom it may concern:

Be it known that I, OTIS B. MORSE, of

Somerswortln in the county of Straft'ord, State of New Hampshire, haveinvented a certain new and useful Improvement in Self-Lubrieating Boxes,of which the following is a description sufficiently full, clear, andexact to enable any person skilled in the art or science to which myinvent-ion appertains to make and use the same, reference being had tothe accompanying drawing, forming a part of this specification, inwhich-- Figure 1 is a verticallongitudinal section of my improvedseltlubrica ting box, taken on the line A B, Fig. 2. Fig. 2 is across-section of the same, taken on the line C D, Fig. 1. Fig.,3 is anend view of the cup and box.

Like letters refer to like parts in the different figures ofthedrawings.

My invention relates to that class of shafting-boxes known asself-oiling, and consists in a novel construction and arrangement of theparts, all as hereinafter more fully set forth, the object being tosupply a more effective and economical box than has heretofore beenproduced. i

In Fig. l, A is the shaft; I3, the box; I', the cover or cap of the box,F F', the oil-reservoirs; G G', the collars or guard-rings; E E', thedrip-cups; and K K', apertures leading from rthedrip-cups to theoil-reservoirs; and X X', chains passing around the shaf't A to thebottom of the reservoirs F F', and operating to raise or convey the oilto said shaft.

In Fig. 2, Gis the hanger 5 A is the shaft; fr, the chain; F,fthereservoir 5 B, the box; 13', the cap 5 m, the cap-screw, and z, thescrew for leveling or truthin g the shaft.

From the above description, the nature and operation of my inventionwill be readily understood by all conversant with such matters.

rlhe reservoirs F F', being supplied with oil as the shaftArota-tes, thechains will be caused to traverse and take up the oil by adhesion orfriction, and lubricate the shaft automatically.

I am aware that one Hamilton obtained Letters Patent of the UnitedStates dated October 2, 1866, numbered 58,409, for an improvement inself-lubricating boxes, in which a chain is used, in combination with acup having two compartments, one compartment of which is designed foroil and the other for water. p

I use the guards G G', arranged on the shaft, as shown. These guards orrings are fitted closelyT to the shaft, and work in recesses out in theupper and lower half of the box, the lower recesses or slots extendingvertically through the box into the reservoirs F F' The slots orrecesses, in which said rings work, are also large enough to prevent therings from coming into contact with the box as the shaft revolves. Theoil taken up by the chains will be conducted along the shaft, or workits way through the .box in the process of lubricating the saine, untilit reaches the guardsV Gr G', where any surplus not required forlubricating purposes will fall into the reservoirs F F', through theapertures in which the lower half of the rings work. Any oil not soreturned to the reservoirs, and which may iind its way outside of therings and drop from the sha-ft, will be caught by the cups E E' andreturned to the reservoirs through the apertures K K'. It will be seenthat in my invention., the oil tanks or reservoirs7 being at the sidesof the hanger, are brought nearer the shaft so that comliiarativelyshort chains can be used, (an important feature,) for when saidreservoirs are so located as to necessita-te the use of long chains, theprocess of lubricating the shaft will be imperfect on account of thesmall quantity of oil they will raise, especially when the shaft isrunning at a low rate of speed. It will also be seen that a box providedwith the reservoirs, as shown, will keep the oil free from all dirt andimpurities, and in cotton and woolen mills will protect it from the finefibers of cotton and wool, which, where the ordinary boxes are used,causes a great waste of the oil. I do not confine myself' to the use oftwo chains and two reservoirs, as shown, as where small boxes arerequired, I sometimes construct them with one chain and one reservoirarranged in the center, and place guards on the shaft each side of thechain, also providing the reservoir with a drip-cup at each end of thebox. I am also aware that in Fig.' 15, Plate 13,

of Hensinger von lValdegg Schmie'rvorrichtungen, a self-lubricatingdevice is shown, in which there is a box containing a reservoir for theoil, and a chain workin g in connection with said box, and the shaft tocarry up or elevate and shaft A, substantially as and for the purtheoil, but said dcvicc is essentially di'erent pose described.
